The 411 was designed by Czerka for use by the Galactic Empire as a hold-out blaster with a relatively long range. During the Galactic Civil War, Alliance to Restore the Republic forces captured the weapon design documents and an entire factory run of the weapon in transit to Coruscant. After this acquisition, the weapon became a favorite of Rebellion espionage agents[2] while undercover.[1] Because of the high-profile nature of the Rebel heist, and the constant rumors that Czerka was in league with the Alliance, Czerka quickly signed an exclusive production contract with the Empire. This agreement was the foundation of Imperial Munitions.[2]
